Answer:
Given sum of interior angles = 1260. n = 13.
Step-by-step explanation:
Therefore the number of sides = 13.
The solution of the equation is as follows;
<h3>How to solve equations?</h3>
An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
In other words, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
The expression can be solved as follows:
b / 27 = - 3
cross multiply
b = -3 × 27
b = - 81
42 = v + 35
subtract 35 from both sides of the equations.
42 - 35 = v + 35 - 35
v = 42 - 35
v = 7
- 128 = 4x
divide both sides of the equations by 4
4x / 4 = - 128 / 4
x = - 32

Answer:
a. FALSE
b. FALSE
c. FALSE
d. TRUE
Step-by-step explanation:
Statement a.
2 (3 - 4 y) = 6 - 4 y
use distributive property on the left:
6 - 8 y which is NOT 6 - 4 y then, FALSE statement
Statement b.
3 + 5 (9 + 2 n) = 48 + 5 n
apply distributive property on the left:
3 + 45 + 10 n = 48 + 10 n which is NOT 48 + 5 n then , FALSE statement
Statement c.
9 - 3 (y - 2) = 3 - 3 y
apply distributive property on the left:
9 - 3 y + 6 = 15 - 3 y which is NOT 3 - 3 y then, FALSE statement
Statement d.
3 (6 x - 2) - 7 = 18 x - 13
apply distributive property on the left:
18 x - 6 - 7 = 18 x - 13 which IS the same as 18 x - 13 then , TRUE statement
